A99 tested on DXO - score: 89

Ive not used the a99 so just my personal impressions.

I think from the reviews before and the sample its quite clear the high ISO of the a99 is not as good as the d600 although its thought to be quite decent.

I think the a99 is alright, but I honestly think its way overpriced, Im not trying to take a dig at people (though saying that hardly helps). Im a little p*ssed off at Sony for that, because Nikon delviered quite a hell of a camera in the d600 and it seems like Sony took their eye off the ball a bit, I just hope they adjust the price and really take a look at why nikon seems to be pulling out more from THEIR own sensor in terms of ISO (the mirror is somewhat an explanation I guess).
